To all whom it ma concern! Be'it knownt atI, JO N A.,ALVEY, a citizen of-the United States of America, residing in the city of StrLouiS andI State of Missouri, have invented certain new and useful Improvements in Bearings for Conspecificationf p The subject. matter of this application is divided'from my. application Serial No; and patented 652,830, filed October 4,1911 May 5,1914, No. 1,095,445.

7 My .iuventionrelates to an antifriction mounting for rollers and is particularly adapted for use in connection with rollers Among the principal objects of my invention are, to provide an antifriction hearing which is capable of maintaining its efii'ciency under conditions subjec'tingfit to end thrust and which may be adjusted to compensate for wear.

Further objects of my invention will more fully appear hereinafter.

The invention consists in the construction and in the arrangement and combination of parts hereinafter more fully set forth.

in the accompanying drawing, which forms part of this specification and in which like reference characters refer to like parts throughout the several views, Figure 1 is a longitudinal section through a bearing embodying my invention, one end of a roller being shown mounted thereon; and Fig. 2 is a view showing the full length of y In the preferred form of my invention shown in Fig. 1, the supports 1 for the bearing spindles 2 are constructed of angle iron.

Only one of these supports is shown, but it is to be understood that this construction is duplicated for the other end of the roller.

Holes 3 are drilled in the vertical leg of the angle iron 1 at suitable distances apart,

and through these holes are passed the bearing spindles 2. The construction of each bearing is the same, and a description of one will suffice for all. The bearing spindle 2 is provided with screw-threads 5 for a portion of its length and is held firmly in position by the locking nuts 4: which are mounted on the threaded portion 5 and enth'ang-leiron 1.," 'i' of which the following a gage opposite sidesof the vertical -leg of Extendifig: f longitudinally bearing spindle 2 munica'tes with a recess -7 in one end of the bearingsp-indle-iand with a recess 8 at the opposite end of said" bearing spindle. L ogrewed' over thend of the bearing spindle 2, adjacent to theflrecesls" 7, is a 'cu'p shaped cap or gland-nut -9, which, in connection with the recess 7, forms" a, chamber 10. Formed on the bearing spindle 2 opposite to its threaded end 5, is *a journal 11 provided with a raceway 12 for "receiving bearing" balls 13. The roller 14, isprefer'ably con structed' of seamless tubing, and in each end of the roller is secured a block 15 A central well or bearingrecess 16 is formed in the outerend' face of said block 15, and is adapted'tdr'eceive the join n'alll. The b'earihg balls 13 in the raceway -12 engage with the circumferential'face 17 of the well 16. In the recess 8 of the spindle 2 is mounted a bearing ball 18 which engages a mating recess 19 formed in the bottom of the well 16.

The angle iron supports 1 are mounted upon bars 20 bent in a U-shape. The verthrough thei isa channel 6 which coin guiding bars 21.

The chamber 10 isfilled with grease or other suitable lubricant, and by screwing the gland nut 9 down over the end of the spindle 2, the grease may be forced from the recess 7 along the channel 6 to the-recess 8. This serves to lubricate the bearing balls 13 and 18. By screwing the locking nuts 4 in opposite directions, the bearing spindle may be adjusted in the'angle iron 1, and when the nuts 4: are jammed tight against the opposite faces of the vertical leg of said angle iron 1, the spindle 2 is held firmly in its adjusted position.

In the modified form of my invention shown in Fig. 2 the supports for the bearing spindles are formed of channels 22. Each channel 22 is provided Witha series of screw threaded openings 23, in each of which the threaded portion of a bearing spindle 2 engages. A single locking nut is provided for each bearing spindle 2 and is mounted on the outer face of the channel 22.

This construction is employed where channel irons are used as supports, because it .would'be difiicult to manilkilulate a locking nut if it were placed in' .t e, recess of the channel. V

Obviously, my device admits of considerable modification without defiarting from my invention, andtherefore to be, limited. to the particular construction which I haveshown and described.

What I claim is: V
